Standard Test Methods for Determining Effects of Large Hydrocarbon Pool Fires on Structural Members and Assemblies
SCOPE
1.1 The test methods described in this fire-test-response standard are used for determining the fire-test response of columns, girders, beams or similar structural members, and fire-containment walls, of either homogeneous or composite construction, that are employed in HPI or other facilities subject to large hydrocarbon pool fires.
1.2 It is the intent that tests conducted in accordance with these test methods will indicate whether structural members of assemblies, or fire-containment wall assemblies, will continue to perform their intended function during the period of fire exposure. These tests should not be construed as implying suitability for use after fire exposure.
1.3 These test methods prescribe a standard fire exposure for comparing the relative performance of different structural and fire-containment wall assemblies under controlled laboratory conditions. The application of these test results to predict the performance of actual assemblies when exposed to large pool fires requires a careful engineering evaluation.
1.4 These test methods may be useful for testing other items such as piping, electrical circuits in conduit, floors or decks, and cable trays. Because failure criteria and test specimen descriptions are not provided in these test methods, testing these types of items will require appropriate specimen details and end-point or failure criteria.
1.5 Limitations -These test methods do not provide the following:
1.5.1 Full information on the performance of assemblies constructed with components or of dimensions other than those tested.
1.5.2 An evaluation of the degree to which the assembly contributes to the fire hazard through the generation of smoke, toxic gases, or other products of combustion.
1.5.3 Simulation of fire behavior of joints or connections between structural elements such as beam-to-column connections.
1.5.4 Measurement of flame spread over the surface of the test assembly.
1.5.5 Procedures for measuring the test performance of other structural shapes (such as vessel skirts), equipment (such as electrical cables, motor-operated valves, etc.), or items subject to large hydrocarbon pool fires, other than those described in 1,1.
1.5.6 The erosive effect that the velocities or turbulence, or both, generated in large pool fires has on some fire protection materials.
1.5.7 Full information on the performance of assemblies at times less than 5 min because the rise time called out in Section 5 is longer than that of a real fire.
1.6 These test methods do not preclude the use of a real fire or any other method of evaluating the performance of structural members and assemblies in simulated fire conditions. Any test method that is demonstrated to comply with Section 5 is acceptable.
1.7 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.8 This standard should be used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.
1.9 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.10 The text of this standard references notes and footnotes which provide explanatory information. These notes and footnotes (excluding those in tables and figures) shall not be considered as requriements of the standard.

INTRODUCTION
The performance of structural members and assemblies exposed to fire conditions resulting from
large, free-burning (that is, outdoors), fluid-hydrocarbon-fueled pool fires is of concern in the design
of hydrocarbon processing industry (HPI) facilities and other facilities subject to these types of fires.
In recognition of this unique fire protection problem, it is generally required that critical structural
members and assemblies be of fire-resistant construction.
Historically, such requirements have been based upon tests conducted in accordance with Test
Methods E119, the only available standardized test for fire resistant construction, However, the
exposure specified in Test Methods E119 does not adequately characterize large hydrocarbon pool
fires. Test Methods E119 is intended to be representative of building fires where the primary fuel is
solid in nature, and where there are significant constraints on the movement of air to the fire, and the
combustion products away from the fire (that is, through doors, windows). In contrast, neither
condition is typical of large hydrocarbon pool fires (see Appendix X1 on Commentary).
One of the most distinguishing features of the pool fire is the rapid development of high
temperatures and heat fluxes that can subject exposed structural members and assemblies to a thermal
shock much greater than that associated with Test Methods E119.As a result, it is important that fire
resistance requirements for HPI assemblies of all types of materials be evaluated and specified in
accordance with a standardized test that more closely approximates the anticipated fire conditions.
Such a standard is found in the test methods herein.
